Does a 20 from a cyclops helm actually qualify as an automatic hit?
Once per day as an immediate action, the wearer can choose the result of the die roll instead of rolling her next attack roll, saving throw, skill check, or ability check.
When you make an attack roll, you roll a d20 and add your attack bonus.
Automatic Misses and Hits
A natural 1 (the d20 comes up 1) on an attack roll is always a miss. A natural 20 (the d20 comes up 20) is always a hit. A natural 20 is also a threat—a possible critical hit (see the attack action).
It seems that the number chosen from the cyclops helm actually doesn't qualify since it's not a roll. Would this be correct?
Edit: I just noticed that the title was incorrect and inconsistent with my real question, it was supposed to be whether the helm qualifies for automatic hits and failures.
